The Earth's magnetic field, or magnetosphere, stretches from the planet's core out into space, where it meets the solar wind, a stream of charged particles emitted by the sun. For the most part, the magnetosphere acts as a shield to protect the Earth from this high-energy solar activity.

The last several years have been a remarkable time for genre TV with shows like Revolution, SHIELD, and Under the Dome. Revolution especially came on strong, but later in the year it faltered after going on a brief hiatus. So now that the show is back, will its audience come back to it as well?

We just reported that late last year, Stan Lee hit the big 9-1, and it’s remarkable that he’s still here, and just as spirited as ever. He’s also been busier than ever, with a brand new TV show, Mighty 7, and an upcoming cameo on SHIELD.

A lot of shows aren’t brilliant right out of the gate. It can often take a while before a show settles into a comfortable rhythm. While SHIELD has gotten stellar ratings so far, some critics feel it hasn’t quite hit the mark just yet, and that there’s lots of room for improvement.

We know it's out there, debris from 50 years of space exploration — aluminum, steel, nylon, even liquid sodium from Russian satellites — orbiting around the Earth and posing a danger to manned and unmanned spacecraft.
